A judge sentenced Eddie Douglas Baker to 45 years in prison for murder--and two additional 10-year prison terms for aggravated assault with a deadly weapon—when Baker pled guilty to all three charges Monday, said court officials.

Baker, 28, was sentenced by 115th District Court Judge Lauren Parish after admitting to fatally stabbing 45-year-old Tana Fuller Warren and stabbing two other persons on or about Feb. 6, 2013. The three sentences will run concurrently, said Upshur County District Attorney Billy Byrd, who represented the state in the cases.

Baker admitted in a videotaped statement to fatally stabbing Warren and putting her in the back of his camper on Ginger Road northeast of Gilmer, according to documents filed in Upshur County Pct. 2 Justice of the Peace Lyle Potter’s office.

Baker and Ms. Warren, who was his girl friend, had gone without sleep for several days while using methamphetamine, and both had high levels of the drug in their bodies, Byrd told The Mirror Monday night.

According to Byrd, Ms. Warren asked Baker to set her free—and the defendant, who was intoxicated on methamphetamine, spotted a knife. The district attorney said Baker related, “I knew what God was telling me. He was giving me the sign” on how to free Ms. Warren.

Baker knew the other two victims, who suffered minor injuries, and it appeared he ran into them while leaving the murder scene, Byrd said. They also had methamphetamine in their systems, the prosecutor said.

Jury selection was scheduled to open in Baker’s murder case Monday, but he decided to plead guilty instead. Longview attorney John W. Moore represented him.
